Ongoing poor service

Booked my phone in with c Surance 28 September 2018 for accidental water damage and received a ticket number 875650. I went back to Cell C savannah on more than one occasion trying to follow up on the repair but I were unable to provide the ticket number since I have lost it. The store just informed me that they will not be able to locate the case without this number. I searched for this ticket numbet since they informed me with no luck finding the number. Since then I received no feedback from the store or head office regarding the claim. Out of the blue I received a call on 30 May 2019 from the store to collect my device , I asked the store employee if the phone were repaired and he were unable to answer me. I went to the store were I had to piont out to the store employee that it would not help charging the phone since the forms claimed that the claim was rejected. I asked the store employee again why was it rejected and he did not know. He then continued to phone C Surance to inquire regarding the rejected claim. They informed him that the IMEI was not completed on the form and I clearly remember asking the store to please fill this details since I were unsure. I am busy cancelling all my contracts with cell c once its due for upgrade due to the service that is up to no good with c surance. This was previously brought under the attention with a previous claim that I had with C surance. I am really done doing business with this company
